The only point I bring up is if the engine has issues when hot and turns over fine when cold , at least that's my take and has 900 miles on it from before it was installed and if the heads are in fact aluminum isn't it sort of a risk to pull the spark plugs when hot ? My guess is Jim suggested doing so with it cold , yet as I said I have no idea what the heads are made of . I just wonder how the engine gets it's cool air through the fan since it's in a T-3 body . I've seen a post on Samba about how one fellow built a special sheet metal cover to adapt the T-4 fan housing's rear most tin to fit the T-3 square bellows . Perhaps this has been done , I've no idea. Also no idea what the operating temp is when this issue crops up. </div><div><br></div><div>William</div></div><div id="m_6528214789166815446DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>

</span>Try removing the spark plugs to see if this seems to free it up. If <br>
so, you're just seeing the compression.<br>
