i have been having a crurping sound coming from my motor around 1500 to2000 rpms any ideas?

[robert graham]

Try running it with the top cowling off to better identify the source of sound?...

What is a crurping sound?

[robert graham]

I think he meant "chirping"?.....a typo?...

[rodbolt17]

typically that chirp is a cyl running lean and backfiring in the crankcase.

can also be a lower main bearing failure.

thanks rodbolt, and yes it was a typo lol I will clean the carbs and do a sync and link and see if that takes care for my problem thanks again
