Steve Sandbrook Posted September 27, 2007 Share Posted September 27, 2007 Just purchased a 1927 Buick and was advised that I need to put an additive in the gas to replace the lead that was used in gas years ago. Is this correct and if so any idea what this product is called and where I can buy this product?I would appreciate hearing from anyone out there who has this vehicle as I am not familiar with the 3 levers on the steering column?Thanks Link to comment Share on other sites More sharing options...
Guest imported_Thriller Posted September 27, 2007 Share Posted September 27, 2007 My understanding is that with the low compression of those engines that you don't need to worry about lead - I don't intend to add anything like that once I get my '29 running.There are Yahoo groups for 1927 Buicks...if you have questions specific to the year, the group consists of folks who are very familiar with these cars. I'm sure someone here ought to be able to help with the spark advance and other levers. I'd asked a bit about that for my '29 on the 1930 Buick Yahoo group...if you don't get a response here soon, I'll dig that up. Link to comment Share on other sites More sharing options...
Guest imported_Thriller Posted September 27, 2007 Share Posted September 27, 2007 Here's the information I got about starting the '29:These cars usually run best with the spark plug gap at .040, but that is notsomething that you have to do. If you are going to pull the plugs you maywant to regap the plugs.Turn on the ignition.Retard (pull down) the spark lever on the left side about half way, pull thethrottle lever on the right down about an inch and push in the starter pedal.It should start right away. Many times, these cars will start withoutretarding the spark.--So, two of the levers are spark advance and throttle. Link to comment Share on other sites More sharing options...
garnetkid Posted September 28, 2007 Share Posted September 28, 2007 There was no lead in the fuel in those years which is why valve jobs were done every 20,000 miles or so. Lead was used to lubricate the valves to keep them from "sticking" to the seats. I would run it till you need a valve job and then have hard seats installed if and when you need to have it done.

Guest imported_Thriller Posted September 29, 2007 Share Posted September 29, 2007 Here it is...I was looking for this thread yesterday, but couldn't remember where it was or what it was titled.Here's the levers on my '29. The lever on the left is for spark advance, and the middle is for lights. I'm not absolutely sure, but believe that the lever on the right is throttle.

jscheib Posted September 29, 2007 Share Posted September 29, 2007 Derek,On my '32, I call the throttle one on the right "cruise control", don't you know. John Link to comment Share on other sites More sharing options...

Mark Shaw Posted October 1, 2007 Share Posted October 1, 2007 Just back from vacation, & I see you guys figured it out! Derek got it right, but you will also need to pull out the choke for cold starts. I have never needed to use the spark advance for starting on 29 or 31 Buicks. I think the spark advance on later cars may be a carry-over from before electric starters when hand cranking with full advance would cause kick backs. 1 Link to comment Share on other sites More sharing options...

jscheib Posted October 2, 2007 Share Posted October 2, 2007 Spark Advance for the '32, still with a crank option, is on the dash board and off the wheel center, just lights and throttle there. I still have my crank but hope it is not needed.John Link to comment Share on other sites More sharing options...
Mark Shaw Posted October 3, 2007 Share Posted October 3, 2007 John, That crank comes in very handy when working on your engine setting tappets, & timing etc. It would be a tough way to start a big heavy six or eight cylinder engine that way.

Dandy Dave Posted October 5, 2007 Share Posted October 5, 2007 Speaking of cranking large engines, I had a Cat Model 50 Bulldozer, (1930's, Gas powered) a number of years ago. Let see.... Yeah, 5 inch bore and 7 inch stroke, no starter. Insert crank, get it in the pin and step down on the crank handle with one foot one the blade and one hand on the radiator for balance. Good thing it started easy. Oh yeah, Don't forget to retard the spark first. Hee he. Dave! Link to comment Share on other sites More sharing options...
