Tap it to 1/4" or 3/8" pipe thread and you shouldn't have any leaking problems. The 3/8" pipe thread is what nearly all briggs engines is tapped to and as darkviper said it's tapered threads. Be sure to use thread sealant on the threads as well. I recommend using the liquid type rather than thread tape. I've seen what thread tape will do to an engine and it's havoc when it happens.
If it's a metal dipstick, here is what I've done in the past. Remove the dipstick and clean with carb or brake cleaner to remove all of the oil residue. I use a black sharpie to color the bottom portion of the dipstick. Then let it air dry for at least an hour. Then install it. It makes it much easier seeing the oil on the dipstick since its dark in color. The marker seems to hold up pretty good but you will have to repeat now and then.
Not trying to start anything because I have no clue about particular engine but being on this forum for a while now, the last couple sentences sound rather arrogant and demanding. Sometimes you have to take the good with the bad, after all its a public forum but maybe someone will be able to help.
No way possible on these eongines. You may have a sheared crank gear key. What kind of flywheel? If ARC what did you set coil gap at? Stock cam or race cam? Solid cast cam or press on lobe cam?Pm sent MowGuard
Jeff, the best I understand it is the billet or any aftermarket valve cover is not legal in the prepared classes. You can use a spacer for the valve cover and I haven't ever heard of a particular height rule on that either. Don't make much since to me as to why its not legal in these classes but that's what they choose. Besides bolting on a billet valve cover is worth an extra 5 horses and we all know that. Lol
All the 49 blocks are the same. Regardless if there is more than one part number it should be same bore. All of the 44 parts will fit except the pistons. While you are at it just send me the 44 block. Lol
