Hi Newbee member here.
I have started a full renovation of 17" super punch, having fully stripped the engine and now rebuilding I have noticed that it has different strength valve springs? which wasnt noticed on strip down! one is significantly thicker and stronger than the other. my question is: which is which exhaust or intake thicker? or has someone just put two dissimilar springs in during previous work from differnt mowers? thanks in advance for any advice and I look forward to getting to more familiar with the site in due course.
