I’m helping a friend with a headless Witte model. Has way too much compression and I’m looking to get the dimensions or a snippet of the drawing of the piston to see how to modify it to reduce the CR. Apparently pistons/kits for this were sold by DeBolt but I don’t see it on his current web site?? He lives several hours from me and this is sort of a surprise for him. He also told me that the kit was offered with pistons for two compression ratios...I’ve seen the two engines with the high and low CRs and both are too high for my liking. Don’t want to violate any copyright concerns so please pm me the portion of the piston from the drawing set. Plan is to make it out of aluminum. Any help appreciated.
