ManxGaz Posted April 2, 2014 Report Share Posted April 2, 2014 I am experiencing fuel in my engine oil when I drain it out at the end of riding. Will adjusting the float height resolve the problem or is there another issue? It is a Blixt Mk1 carb. Thanks in advance for any help.

p'boro lad Posted April 4, 2014 Report Share Posted April 4, 2014 What size jet do you have in? Quote Link to comment Share on other sites More sharing options...
ManxGaz Posted April 4, 2014 Author Report Share Posted April 4, 2014 Not entirely sure as I have bought the bike second hand for use in amateur meetings. It is still in its original set up. Stripping the carb is my project for the weekend. It starts easily and runs fine, but when I drop the oil it is contaminated with fuel. Do you think a smaller jet would help?

phillwhitewasmad Posted April 4, 2014 Report Share Posted April 4, 2014 How much methanol in oil if lots check the choke if full I have small amounts in mine put it down to not riding fast enough Quote Link to comment Share on other sites More sharing options...
ManxGaz Posted April 4, 2014 Author Report Share Posted April 4, 2014 It's quite substantial. I use the choke for starting but turn it off immediately the engine is running. I am stripping and cleaning the carb to see if this makes any difference. Have been advised that it may be over fuelling if the floats are not closing off the inlet to the bowl?

stutowner Posted October 14, 2018 Report Share Posted October 14, 2018 it's not unusual as long as the oil is not washed off the cylinder surface due to over jetting. Quote Link to comment Share on other sites More sharing options...
