Low compression in one cylinder options

Rotag01

I have a cart and it runs but evidently not well no power one cylinder has 65 and other is 150

So would i be best off to just put rings in it or should I go the whole route and try to tackle a rebuid myself ?

Maybe send it off to one of the rebuild places?

I have another cart I want to put a vegas carts in but wife and grand daughter will be driving this one so I want it easy to operate.

Adjust the valves and recheck compression.

I adjusted them but will recheak them tomorrow

I was hoping for you a valve was tight, not closing... rather than leaking
I suspect valves because ring wear would be more even.

Explaine a little if you think its valves ordering a ring set wont help

So been reeding up on valves I have 2 other heads sitting here at the house Should I just pull the ead and see if its the problem?


I also have an extra block etc.

Squirt some oil in the low cyl and try again. If compression goes up a lot, you have bad rings. If it says same, it's almost certainly valves.

I put some sea foam in it before this post ran it up and down a few times and checked it still around 60. I also re adjusted the valves. I think it maybe a babe but with blue smoke and all I am worried about the rings also.

I have an extra complete engine sitting here so I am going to tear the extra one down for practice

Rotag01

If the extra can be rebuilt I will rebuild it and stick it in the cart when I pull out the old one

Mind change a complete rebuild kit 700 to 800

I can do and engine exchange for same money and not burn up my off time
