I’ve not done this... but I’ve read a lot and looked in the manual... as far as I know they are replaceable. They press out/in.. if you have a press or access to a press should be a easy fix... I think there’s more to it though... If I’m not mistaken they have to have the right angle on them... but I’m almost positive they’d have a guide built in for them to set in the angle or straight as they’re supposed to.... again I haven’t done this, so don’t take my word for it. Just advice... hopefully the “pro’s” will chime in.. I’m just average shade tree mechanic

**also, pics are great! Be sure and post some as well**

Dam man... that’s a bummer. I thought for sure you could press them out... thought the same on my old crank, but couldn’t get it to budge..

Yea, better safe than sorry! Hope you get it running soon, good luck

They can be replaced. They can't fall into the engine. Send the head to a reputable shop that deals with these. Millennium Technologies is a good place for things like this. The valve seats will need machined after the guides are replaced. I strongly recommend new valves if that wasn't part of the plan. Ferrea are the most reliable valves for these engines.

i think the guide replacement with the shop gonna cost more so....
im not at usa also, the shops here are pretty crapy/Unprofessionals...

It can be made to fit, but it's not a direct swap. The intake port is at a different angle, and will change where the carb is located. The coolant hose is in a different location also.
