Rebuilding Kohler

Re: Refreshing Kohler

I thought a valve tap was caused by too small of a clearance thats why i talked about grinding the stem. I didnt touch the synchro balance. The points and condenser were replaced a couple months before i took the engine apart. I thought there was only one place to put the dipstick tube. I pulled the dip stick out and it wasnt bent or chewed. There is a another dipstick that screws into the oil pan at a 45 degree angle which could be the problem. There is another one on the opposite side but it just has a plug. I think it was off of compression release CAnt remember its been a while Im going to go check those things now.

There is still a tinking sound. There was about an 8th inch gap between the valve and the tappet. It wasnt like that when i put it together. It would sound like a brand new engine if i could get rid of the tapping. Im going to see if the gap got larger again.

Re: Refreshing Kohler

Take another look at your valve adjustment procedure in the manual. Follow it step by step. They should mention making sure it's not on compression release. Hopefully that will get you straightened out. I'm going to be away till next friday, so if you continue to have problems, I'm sure someone here will be able to help you through it. Good luck and I'll check up on you next week.

Re: Refreshing Kohler

Well i redid the valve to tappet clearance again and have seen no improvement. Would i see an improvement? What else could be the cause of the tapping? Is this bad for the engine? Is the tapping from the stem hitting the tappet or the valve hitting the head?

I had to reset mine 3 or 4 times before I got them set just the way I wanted. Have patience and keep trying. You're doing good so far. /w3tcompact/icons/smile.gif

Re: Refreshing Kohler

qwerty-1/8th of an inch is too much valve clearance, and I would think eventually would damage something. Most engines have valve clearance measured in thousanths of an inch. Some service manuals give valve clearance specs in millimeters. if you are reading a metric spec but using SAE feeler gauges the valve clearance will be too large. Example: .05mm=.002" in. You may be thinking you are setting the clearance to .05mm(.002"in) but are really setting it to .050" in. (1.22mm). The reason I suggest this is that 1.22mm is very close to 1/8th of an inch (which you say is the current valve clearance).

Metric mesurements are easy if you remember this golden conversion: .002"inch=.05mm

Re: Refreshing Kohler

What type of valve adjuster does the engine have(if any)? In some small engines the valve stem must be ground to increase clearance. Does it have a screw and a locknut? Is there a shim type adjuster? Is this a side valve or overhead valve? Is it overhead cam? I dont know Kohler engines as well as Kubmech.

Re: Refreshing Kohler

Everything is good now. I adjusted the clearance again today and finally got it right. Engine sounds great!!! I drove it around for half an hour today so i have about 45 min on it total. This was a very enjoyable learning experiance and would like to thank everyone for helping me through this. I couldnt have done it without you!

/w3tcompact/icons/smile.gif Glad it worked for you. Now that you got that first engine under your belt, you are on your way.
