Carbs?

Post: # 11563Post luckydog »

Ok been bothering Hipster and Chet about a stumbling Looper 150.
-Cleaned carbs
-sprayed with cleaner/ rinsed with gas
-don't have compressed air to blow out orifices (this could be it)
-changed plugs
-compression decent
-will not wind out
-hard to start cold
-hard to get on plain
be more vigorous with the carb. cleaning? Any tips? Suggestions? First time out had little hints of full power now, not so much... :)

I was warned not to soak carbs too long in cleaner as it can eat away at things...Lots of black s@#$ coming out the exhaust.

Did you find the carb that was flooding when we test fired it? It could be flooding. With the new plugs can you see a difference in any of them?

If you use the stuff I gave you, you don't have to worry it won't do any damage like the dip tanks will. The jets should come out nice and shiny.

Another thing to check is the lever on the choke.
