1. Yes, you can convert the D-8800 motor to direct electric start, it's not relatively inexpensive either, figure $1000 at least, you may also be able to fix your starting engine for the same $$. Don't think you have to be concerned about matching the flywheel teeth on this model, your starter supplier will know. 2. If you need to start it in cold weather, you may not like how direct electric start performs on an old technology motor like the D-8800 4Cyl. CAT. 3. I will admit, these little 24hp vertical 2 cyl. starting engines can be fussy sometimes, require some work to keep in good running order, but there are big advantages that come with them. You can spin the main as long as you want, warm & circulate the fluids, see oil pressure rise, all before giving it fuel, you cannot do that with direct electric start, and in the cold it's going to be a harder battle to fight to get it running. 4. If you, keep your sediment bowl/ fuel tank, clean, use solid copper plug wires, the right spark plugs, keep your magneto in good shape/or have rebuilt if necessary so it fires a hot spark, motor is in good shape internally, carb. clean, keep oil clean and changed, drain carb bowl after pony shuts down to keep fuel from seeping into the oil, ( has ruined many by letting gas thin the oil ) they are durable and will do the job as designed to, you just have to make sure it's in good shape. Sometimes you may have to adjust your pinion latches to disengage from the main correctly after it starts. Once you have one in good shape, keep it protected from the elements, keep your magneto covered etc. it should run fine for quite some time. 5. Yes you can take it off as a unit, the manual will describe that, look on e-bay for a servicemans reference book for a D7 3T and a parts manual for same, they will be very helpful. They also seem to be for sale quite often, original's in good shape, I think caterpillar offers them through their Legendary Literature and Midland Press offer's a good reproduction, be aware that some reproductions are not good quality. Also, the 3T was made from 1944 to 1955 if I remember correctly, well over 22,000 units made, 9,999 4T's and 9,999 7M's which are all practically identical D-7's, parts books are the only way to see what may differ as the s/n's progressed, which means there should be good resources still available for these, Hope that helps & here is the link for ACMOC:
