drdon Posted October 25, 2019 Share Posted October 25, 2019 Here is one really stumping me. My recently finished 37 CE really isn’t. i am having problems with float needle and seat. I have tried 3 different needles- 2 NOS, and 3 different seats. No matter what combination I use, I get a stuck open needle and gas running out of the top of the float chamber. But only now and then not all the time! i have also rechecked the float for proper position in the bowl by measuring to equal recommended setting. The fuel pump is original engine driven pump so it seemingly can’t be too powerful. WTF! HELP! I don’t want to burn this thing up going down the road.

chris piazza Posted October 25, 2019 Share Posted October 25, 2019 Is the check valve still present in the fuel line going into the carb? Link to comment Share on other sites More sharing options...

Spinneyhill Posted October 27, 2019 Share Posted October 27, 2019 Do you have a fuel filter in the line? I get that sometimes: a speck of something gets under the needle. Link to comment Share on other sites More sharing options...

There is a very good video on youtube by Uncle Tony ( Uncle Tony's Garage ) that deals with all kinds of trouble shooting on carbs.

drdon Posted November 2, 2019 Author Share Posted November 2, 2019 I think the fuel filter was the answer. On inspection I found fine sediment in the float bowl- had to come from somewhere! installed an inline fuel filter last week. So far so good. Thanks....
