Where did that come from? He doesnt have to remove the hotstart nut, being that its on the carb.

Good advice, but I cant relate the two?

if you read the owners manual it actually tells to you to remove the hot start cable from the carb. It gives you a bit more clearance to remove the valve cover..

I went by the manual the first time i ever checked my valves and i learned the hardway that it was a bitch to put back.

Well, it does also reduce the risk of breaking the aforementioned, ridiculously fragile nut, but you have to watch out for manuals sometimes. They used to tell you to drain the coolant and remove the right radiator, too.

I've had mine on and off 5-6 times, and the plastic one is still great!:cool:

Same here, just use the right size wrench and you should never strip anything :applause:
