i need advice... searching thru my posts hasn't bred success. I saw someone post about differences in NOS and aftermarket pushrod seals. One has a lip, requiring more work, one is flat edged with a simple install after deburring, which is which? and where can I find them? I also wanna know where the best quality single push rod can be found, and what all I need to install it... been searching for hours, and despite being only 22, and quite proficient in internet searching, I cannot find the information needed to have confidence in purchasing the parts for my specific situation. In all, I need new push rod seal, new bushing, new chain and sprockets, air filters, starter button, and probably other stuff I’m unaware of... I’ve been skeptical of MikesXS because I’ve heard some negative comments. Just trying to get my order right the first time and avoid the returned item process... help me find the right resources please!!!
